Isaac J. Manjarres 77c20b4cbc iommu/dma: Trace bounce buffer usage when mapping buffers 
commit a63c357b9f upstream.

When commit 82612d66d5 ("iommu: Allow the dma-iommu api to
use bounce buffers") was introduced, it did not add the logic
for tracing the bounce buffer usage from iommu_dma_map_page().

All of the users of swiotlb_tbl_map_single() trace their bounce
buffer usage, except iommu_dma_map_page(). This makes it difficult
to track SWIOTLB usage from that function. Thus, trace bounce buffer
usage from iommu_dma_map_page().

Fixes: 82612d66d5 ("iommu: Allow the dma-iommu api to use bounce buffers")
